도 2는 본 발명의 실시예에 따른 음성통신 서비스 상호 인증 방식을 도시한 도면이다. 이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다. 2 is a diagram illustrating a voice communication service mutual authentication method according to an embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 실시예에 따른 음성통신 서비스 상호 인증 방법은, 사전에 사용자가 음성통신 서비스를 사용할 소프트웨어 또는 단말기(특정 전화번호를 갖고 있는 사용자 전화기, 특정 스마트폰에 설치된 앱, 인공지능 스피커에 설치된 앱)와 해당 소프트웨어 또는 단말기의 고유값과 연관된 통신이 가능한 인증단말기를 음성통신 서비스 기관에 미리 등록해 놓은 상태에서, 해당 음성통신 서비스를 받기 위해서 음성통신 서비스를 이용하는 소프트웨어 또는 단말기로 음성통신 서비스로 접속을 시도하면, 해당 음성통신 서비스 서버가 접속을 시도한 소프트웨어 또는 단말기의 고유값을 자동으로 인식하고, 해당 고유값과 관련하여 서비스 인증값을 생성한 후 사용자가 접속한 음성통신 서비스 채널로 들려주면서, 해당 고유값과 관련된 인증기로 음성통신 확인용 인증코드값을 전송하거나 생성하도록 명령을 전달하고, 사용자가 음성통신 채널로 들은 인증값과 인증기가 표시하는 인증값이 같은 경우 사용자가 음성통신 서비스를 먼저 확인하고, 인증기에서 확인 버튼을 누를때 인증기가 그 시점에 생성한 사용자 인증값을 서버로 재차 전송하여 서버 역시 사용자를 인증한 후 음성통신 서비스를 계속 하는 진행하는 음성통신 서비스 상호 인증기술을 제공한다.The voice communication service mutual authentication method according to an embodiment of the present invention is a software or terminal (user phone with a specific phone number, an app installed on a specific smart phone, an app installed on an artificial intelligence speaker) that the user will use the voice communication service in advance. ) and an authentication terminal capable of communication associated with the software or terminal's unique value has been registered in advance with the voice communication service institution, and is connected to the voice communication service with the software or terminal that uses the voice communication service to receive the corresponding voice communication service. is attempted, the corresponding voice communication service server automatically recognizes the unique value of the attempted software or terminal, generates a service authentication value in relation to the unique value, and plays it through the voice communication service channel accessed by the user, A command to transmit or generate an authentication code value for voice communication confirmation is transmitted to the authenticator related to the corresponding unique value. Provides a voice communication service mutual authentication technology that continues the voice communication service after verifying and re-transmitting the user authentication value generated by the authenticator to the server when the confirm button is pressed on the authenticator, and the server also authenticates the user do.

일 예로, ARS 기기가 발신자의 전화번호를 자동으로 인식하고 해당 전화번호가 사전에 음성통신 상호인증서비스에 등록된 전화번호라면 해당 음성통화 채널에 그 당시 생성한 일회용 임시번호를 음성통화채널로 알려주면서, 해당 음성통화 채널 이외에 다른 인증기기를 통해 음성통신 인증값을 표시하고 사용자가 음성통화 채널로 들은 인증번호와 인증기에 표시된 인증값이 일치하는 경우 이를 확인하도록 하고 확인시 사용자 인증값(OTP, 안면인식, 지문인식, 음성인식)을 인증기를 통해서 서버에 전송하게 하여 서버 역시 사용자가 정당한 사용자 인지 확인 한후 서비스를 계속 이어갈 수 있도록 허락하는 음성통신 서비스를 구현할 수 있다.For example, if the ARS device automatically recognizes the caller's phone number and the phone number is registered in the voice communication mutual authentication service in advance, the one-time temporary number created at the time is notified to the voice communication channel. In addition to the corresponding voice call channel, the voice communication authentication value is displayed through another authentication device, and if the authentication number the user hears through the voice call channel matches the authentication value displayed on the authenticator, check it. Facial recognition, fingerprint recognition, voice recognition) can be transmitted to the server through the authenticator, so that the server can also implement a voice communication service that allows the service to continue after confirming that the user is a legitimate user.

상술한 바와 같은 본 발명의 실시예에 의하면, 해커가 사용자 휴대폰에 멀웨어를 설치함으로써 사용자가 정당한 공공기관 전화번호로 전화를 하더라도 상기 멀웨어에 의해 해커에게 연결되도록 처리되는 경우에도, 전화로 연결된 해당 서비스가 실제로 정당한 공공기관에 의한 음성통신 서비스인지를 음성으로 직접 확인할 수 있기 때문에, 해당 사용자가 보이스 피싱 위험에 노출되게 되는 위험성을 감소시킬 수 있다.According to the embodiment of the present invention as described above, even when a user calls a legitimate public institution phone number by a hacker installing malware in a user's mobile phone, even when the malware is processed to be connected to the hacker, the service connected to the phone Since it is possible to directly check whether the service is a voice communication service by a legitimate public institution, the risk that the user is exposed to the risk of voice phishing can be reduced.

또한 상술한 본 발명의 실시예에 의하면, 음성을 기반으로 하는 다양한 서비스들(예를 들어, 폰뱅킹, AI 스피커 뱅킹 서비스 등)에서 사용자에게 인증 코드값(예를 들어, 일회용 비밀번호 또는 비밀번호)의 입력을 요구하는 게 아니라 음성통신 서비스가 사용자에게 해당 서비스에 관한 서비스 비밀번호를 음성으로 알려주고 사용자에게 확인하게 함으로서 비밀번호 또는 인증값 관리를 개선할 수 있다.In addition, according to the above-described embodiment of the present invention, input of an authentication code value (eg, one-time password or password) to the user in various voice-based services (eg, phone banking, AI speaker banking service, etc.) Password or authentication value management can be improved by allowing the voice communication service to voice the service password related to the service to the user and confirming it to the user instead of requiring it.

이상에서는 본 발명의 실시예를 참조하여 설명하였지만, 해당 기술 분야에서 통상의 지식을 가진 자라면 하기의 특허 청구의 범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 쉽게 이해할 수 있을 것이다.Although the above has been described with reference to the embodiments of the present invention, those skilled in the art can variously modify the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below. And it will be readily understood that it can be changed.
